Students and parents both sign a release. This isn't a local thing guys, it's federal law now. If school's don't filter/monitor, they lose federal and state funding.
Whatever it is, it must be heriditary. My dad and sister both do it too. I read an article a long time ago that mentioned it as an allergy, but can't remember the actual name for it.
Maybe so, I haven't tried that. It would depend upon the user changing it though which eliminates most regular users. We do have the IP addresses for the OSCAR servers blocked as well.
Maybe search warrant isn't the correct term.. subpoena maybe? Anyway, it was a request to them to provide information on what IP address was logged in as that username at the time the threat came in.
As Manager of Technology for a school system, we made the decision to shut down all AIM ports because there is currently no way to monitor, filter, or track instant messages that go across it. Local, state, and even federal programs require that we monitor and filter all Internet access by minors. After having some incidents with AIM (including a bomb threat that AOL would not trace for us, even with a search warrant from the FBI), we shut down all Internet-based instant messaging programs.
The bandwidth use is negligible.. especially in these days of cheap bandwidth for education (we have a full DS3 45Mbps for a 7500 student district). The liability of having Internet traffic that is basically untraceable without a sniffer is something we can't have.
We use the RImage Desktop product to duplicate our CDs. Load up 50 blanks in the hopper and start burning. The arm grabs a CD, puts it in the printer to print the label, removes it from the printer and puts it in the drive, burns the CD, and places it in the output hopper. The model we have is pretty old and is SCSI based. Their new ones are Firewire and much faster than ours. We plan on upgrading in the spring.
You might want to check your sources. Netware6 still requires a DOS partition to boot from although the installer will create it for you (so would Netware 4.11 and 5.X).
The more recent ReiserFS is much more stable. We run it on a RAID5 system that serves e-mail for about 7000 users. We use Maildir format mailboxes and ReiserFS is supposed to be really fast for small files. We converted from a dual-550 to a dual-1.26 system and went from ext2 to ReiserFS and noticed a huge speed increase in opening large mailboxes.
We started using Vexira (http://www.centralcommand.com) Mail-Armor this year. We use Debian/Exim for about 8000 users for a school system. The setup was very simple. Mail-Armor listens on the SMTP port and does real-time scanning of every message that goes through. It then passes the message on to the "real" SMTP server running on a non-standard port. We were initially worried about whether it could keep up with our traffic, but it has been flawless so far. It uses two processes: one listes on the SMTP port and does the scanning while the other processes the queue and passes the messages on to Exim.
It notifies the postmaster and both the sender and receiver when it detects a virus. A cron job runs every night to download the virus definitions. It cost $150 for a school system. The cool thing is that it is licensed by domain, not by # of mailboxes like some products.
I know Compaq, HP, and some specialty educational "mobile lab" companies make laptop charging stations. They have a space for the laptop and one extra battery for each. The one I looked at even had a spare power plug so the student can go to the station, plug in the laptop, swap the batteries, and unplug the laptop without shutting down or losing their work. I'm not as familiar with Dell, but at least call their education department and check with them. If they sell mobile labs, it's a good bet that they have something similar.
You'd really be better off going with fiber for gigabit. Yes, Cat5e (and regular 5 if terminated correctly) will run gigabit, but there are some idiosyncracies that you might run into. Your NIC manuals should specify the requirements, I can't remember them off the top of my head. Also, we've found that different vendors support gigabit in slightly different ways on copper. We can't get SMC 1000-BaseT and Cisco 1000-BaseT to talk to each other. We ended up swapping out all our 1000-BaseT links to fiber and haven't had any troubles since.
So, go fiber if at all possible. If you absolutely have to use copper, use 5E cable from a reputable vendor (Belden, Berk-Tek, Mohawk, etc.) and use GOOD jacks and patch cords. I prefer Panduit and spec it for all our jobs, but others also make good stuff. Don't scimp on the patch cords either, these cheapies that you find many times don't test real good. Go for 5E rated patch cords with the short plugs and gold contacts.
I agree. We have users call the help desk pretty often when they have to force a reboot of their Windows machine. It of course runs scandisk while booting and then asks them what to do if it finds problems. They are very puzzled when their mouse doesn't seem to do anything (you have to use the arrow keys to select the options). Text-based interfaces just aren't intuitive to many modern users.
Have you read any of Weber's Honor Harrington series? I think they're great as long as you keep in mind that they are truly of the "space opera" genre. Having them all on one CD will be very handy!
Price fiber vs copper installations with connectors and labor. The defacto standard Siecor Unicam connectors used by most fiber installers run around $9/each. For a large install, you're looking at a huge cost increase. For desktop installs with two ports, that's $72 just for connectors for one station! Panduit Cat 5E jacks on the other hand are about $3.50 each, so $14 for two ports in this case. Labor costs are also higher since it takes time to strip, clean, and terminate.. even with the Unicams. That isn't counting fiber trays and the higher cable costs for fiber vs copper. It just isn't practical for most companies except between closets or for special applications.
Yep, Belden Datatwist.. I bought 40,000 feet of it for an install a few years ago. It at least doubles your install time and tests no better than the other 5e cables according to our meters. We did find that the stripper they provide is almost useless though. Take your dikes and cut between the pairs then use your fingers to pull them apart enough to terminate. I was glad to see that last roll be used up though!
Large networks require high-density switches with fast backplanes. It's cheaper and easier to buy a couple of large switches than to buy a lot of smaller ones. Also, in the pre-switch days, you ran into the 4-repeater rule which prevents you from daisy-chaining more than five segments together without a router or bridge.
In practice, you generally have a main distribution (MDF) located centrally in a building.. normally where your server(s) are also located. If distances or practicality prevent you from running all your cables to the MDF, you place one or more intermediate distributions (IDF) in convenient locations. The IDFs normally have workgroup or stackable switches tied back to the MDF via fiber. The MDF has some type of backbone switch (preferably a Layer-3) or router connecting all the IDFs to the MDF which has it's own workgroup/stackable/chassis switch. All new installs should be Cat 5E or better to all workstations for switched 100 with gigabit fiber between the switches. That's the way we do it anyway.
I just got a Palm M515 and use ActionNames and PocketMirror to sync with Outlook. It syncs everything as far as I can tell.. even notes for meetings and contacts are synced properly with Notes in Outlook. It actually seems to work better for me than the iPaq I used to have.

5190 outgoing needs to be open for OSCAR to authenticate to the AOL servers .. shut it down and AIM users can't login at all.

Are there are Cracker Barrell restaurants in your area? Around here, they carry gyros, Rubik's Cubes, etc.

MacTCP supported BOOTP, but not DHCP, you didn't get it until OpenTransport came out. I know it well, we used to support several hundred of them :)

All the recent versions of Works that I've seen include Word as the word processor.
Don't be an idiot, termination in this respect means terminating the cable onto the jack/patch panel.
